This page contains a list of libraries and tools in a certain category. For a comprehensive list of such pages, see Applications and libraries.
Tools for interfacing with other languages
Haskell's built-in features for interfacing to other languages are formally defined in the Foreign Function Interface (FFI) section of the Haskell 2010 Language Report. You may learn it by example at the IO inside guide.
See also Web services and RPC.
The following tools and libraries either simplify interfacing to C or allow interfacing to other languages and environments (COM, JVM, Python, Tcl, Lua...).
- inline-c uses quasiquotation to seamlessly call C libraries and embed high-performance inline C code in Haskell modules.
- A lightweight tool for implementing access to C libraries from Haskell.
- A tool to create Bindings-DSL based interface files for C libraries.
- Haskell FFI Binding Modules Generator (HSFFIG) is a tool that takes a C library include file (.h) and generates Haskell Foreign Functions Interface import declarations for items (functions, structures, etc.) the header defines.
- A tool to simplify the process of interfacing C libraries to Haskell. It is less powerful than HaskellDirect, but easier to use and more portable.
- A binding to libffi, allowing C functions of types only known at runtime to be called from Haskell.
- Call any JVM function from Haskell
- This package offers bindings to the Java Native Interface and a high level interface generator.
See also the discussion on Haskell Cafe.
- Bindings that allow Haskell code to call CPython code.
- MissingPy is really two libraries in one. At its lowest level, MissingPy is a library designed to make it easy to call into Python from Haskell. It provides full support for interpreting arbitrary Python code, interfacing with a good part of the Python/C API, and handling Python objects. It also provides tools for converting between Python objects and their Haskell equivalents. Memory management is handled for you, and Python exceptions get mapped to Haskell Dynamic exceptions. At a higher level, MissingPy contains Haskell interfaces to some Python modules.
- A Haskell-C++ Foreign Function Interface Generator
- An interface between Haskell and Squeak, a freely available Smalltalk language and environment.
- lp2fp is a program-translator from Prolog to Haskell.
- HaskellScript is the collective name for all Haskell components, both tools and libraries, that allow interaction with the COM/ActiveX framework.
- TclHaskell is a haskell binding to Tcl-Tk that lets you build GUIs in Haskell. It is Haskell 98 compliant. It has been tested under hugs98 and ghc-4.04.
- A hackish method calling C++ from Haskell.
- Re: [Haskell] C++ bindings.
- An e-mail describing how to link to C++
- Haskell interface to Lua scripting language (tested with GHC 6.6/6.8).
- Haskell interface to R
- An experimental .NET Bridge for Haskell.
- Impersonates an Erlang node on the network.
- Guide to Haskell's Foreign Function Interface
- Comparision of the different tools.
- Green Card
- Green Card is a foreign function interface preprocessor for Haskell, simplifying the task of interfacing Haskell programs to external libraries (which are normally exposed via C interfaces). Green Card is currently able to generate code compatible with Hugs and nhc. Green Card is compatible with the Glasgow Haskell Compiler (GHC), versions prior to 6.2.
- Green Card is not compatible with GHC versions 6.2 and later because Green Card uses a deprecated form of Foreign Function Interface (FFI) binding, _casm_: such old-style bindings were removed in GHC version 6.2. See ANNOUNCE: GHC version 6.2.
- HaskellDirect is an Interface Definition Language (IDL) compiler for Haskell, which helps interfacing Haskell code to libraries or components written in other languages (C). An IDL specification specifies the type signatures and types expected by a set of external functions. One important use of this language neutral specification of interfaces is to specify COM (Microsoft's Component Object Model) interfaces, and HaskellDirect offers special support for both using COM objects from Haskell and creating Haskell COM objects. HaskellDirect groks both the OSF DCE dialect of IDL (including the various extensions introduced by the Microsoft IDL compiler) and the OMG IIOP/CORBA dialect. Not compatible with recent versions of GHC (6.6.1)
- A hybrid language of Java and Haskell.
- A Java Native Interface for Haskell. Allows Haskell to invoke Java code. Includes a tool to generate Haskell bindings for a Java library. Works for hugs and ghc under both Linux and Windows. (Based on Greencard, see above.)
- Haskell/Java VM Bridge
- A bridge to the Java virtual machine via JNI for Haskell.
- Lambada (PDF)
- A Haskell <=> Java inter-operation bridge. Inter-operation between Haskell and Java is provided by Lambada via the Java Native Interface (JNI), giving you a set of Haskell abstractions that lets you both call out to Java from Haskell *and* wrap up Haskell code behind a Java-callable veneer. Not compatible with recent versions of GHC (6.6.1)
- A set of patches and additions to GHC that let GHC compile from Core to JVM bytecode. Also has a FFI for calling native Java libraries.
